| Abstract: | The optimum technological conditions of the synthesis of diethyl sebacate by the reaction of sebacic acid and ethyl alcohol with SO 2- _4/Fe_2O_3-TiO_2 as catalyst were studied. The results showed that the yield was over 96% when molar ratio of ethyl alcohol to sebacic acid was 4.0∶1, reflux reaction time was 3.5 h and amount of catalyst was 5% of sebacic acid.This process has many advantages such as higher yield, simple procedure,shorter reaction time, non-corrosive,non-pollution, and the catalyst could be recovered, reactivated and reused for 10 times. |
